This paper deals with the distribution of liquid pressure and the porosity within filter cakes formed inside of curved leaves - mainly spherical ones.
The particle structure of the cake for outside filtration under constant applied pressure is held overall in the compressive equilibrium state, but the compressive pressure at some small element of the cake for inside filtration is released. From this conception, the cake was divided into three parts- the incompressible part, the compressible and equilibrium part, and the compressible but released part-, and the liquid pressure and porosity were analyzed. The results of the numerical calculation were compared with the experimental data and the influence of leaf resistance on the soil compressive pressure are discussed.
